and for the harvesting of the seed from the second crop. The 

 mixed grasses yield from 1 to 2 tons per acre, with an average yield 

 of about 1 tons. Clover alone yields about the same, while the seed 

 is harvested from the second crop, giving yields from 1 to 6 bushels 

 per acre. 



In the extreme western region of its occurrence flax and spelt are 

 also grown. 



In the older settled communities, where regular crop rotations 

 have been adopted, and particularly where corn may be successfully 

 grown, dairying and stock raising have become established indus- 

 tries upon the Carrington silt loam and associated soils. As a result 

 considerable areas of the type are devoted to pasturage and the 

 greater part of the grain and hay produced upon the soil is fed to 

 the farm stock. In such areas a money crop is frequently grown. 

 In southern Wisconsin this crop is usually the binder tobacco, giving 

 yields ranging from 1,000 to 1,500 pounds per acre and averaging 

 about 1,200 pounds. In other localities potatoes, sugar beets, and 

 cabbage constitute the supplementary crops raised in conjunction 

 with the grains and grass. 



The Carrington silt loam may therefore be characterized as a 

 fertile and valuable general farming soil, chiefly devoted to the pro- 

 duction of corn, wheat, oats, and hay, but also used to a limited extent 

 locally for the production of special crops. 



FARM EQUIPMENT. 



In the dairying sections the Carrington silt loam usually carries a 

 complete equipment of substantial farm buildings. In the grain- 

 growing regions the building equipment is less elaborate, but suffi- 

 cient for the farm. In all areas where it occurs the farm live stock 

 is well up to the average, and in all cases heavy draft animals are used 

 for the tillage of the type. The equipment of farm machinery is 

 also well suited to the cultivation of a heavy and fertile soil. Im- 

 proved farm machinery is characteristic of the region where this 

 type occurs most extensively. 



SUMMARY. 



The Carrington silt loam is an extensive and valuable general 

 farming soil found upon the uplands of northern Indiana, southern 

 Wisconsin and Minnesota, and in the eastern portions of both North 

 and South Dakota. 



Over the greater portion of the type the drainage of soil and sub- 

 soil is adequate. In minor, depressed areas tile drainage is neces- 

 sary for the successful cultivation of tilled crops.
